Multi-channel, multi-rate Ethernet aggregator - 10G to 400G AX (e.g., AI)

Overview

OmegaCORE 400G AX is a multi-channel, multi-rate Ethernet aggregator that supports tributaries from 10GE, 25GE, 40GE, 50GE, 100GE, 200GE and 400GE in combinations up to a maximum of 400GE.

Ultra-low Latency: 400G MAC+PCS+FEC (roundtrip) < CALL. This Core provides FlexE 2.1/2.0/1.1/1.0 functionality and implements multi-rate Ethernet PCS and MAC. This versatile device allows users to add or drop sub-channels (for example 10GE) or merge channels (for example 4x25G = 100GE). These dynamic changes do not affect traffic on existing channels.

The north-bound interface from the multi-channel MAC provides a configurable system interface. The multi-channel MAC manages the mapping between individual MACs and the assigned I/O or I/O group.

The southbound interface is mapped (at the PMA layer) to the on-chip SERDES. The core is responsible for channel alignment and FEC (where applicable).

Benefits

  • Optimized to work with 112G /56G SerDeses
  • Combines Ethernet streams at a variety of rates to a single multi-channel interface at MAC
  • OmegaCORE 400G_AX allows access connections supporting 10GE, 25GE, 40GE, 50GE, 100GE, 200GE and 400GE in any combination on  any port or groups of ports to a maximum total bandwidth of 400Gbps
  • Ultra-low latency and area efficient FEC Core supports LL FEC RS(272,258), KP4 FEC RS(544,514), KR4 FEC RS(528,514) and FC FEC (2112,2080)
  • Support up to a maximum of 4 / 8 channels (fully optimized) and design for ultra-low latency, low power and area
  • Off-the-shelf, proven technology implementation in ASIC SOC
  • Dynamically change rate on any port without affecting existing traffic
  • Tested and interoperability-proven against 3rd party
  • Optional 1GE/SGMII add-on
